The headphone icon that doesnβt disappear from the Xiaomi Redmi 9 notification panel is a common problem with hardware or software failures. Even if you havenβt plugged in the headset, the phone may βthinkβ that the device is still inserted into the 3.5mm connector, which interferes with sound playback through speakers, blocks the microphone, and creates discomfort when making calls.
In 80% of cases, the error occurs due to contamination of the connector, oxidation of contacts or failure of the audio driver. Less often, mechanical damage to the socket or incorrect settings of the system. In this article, we will discuss 5 working ways to remove the icon of headphones - from simple (reboot) to complex (disassembly of the phone).
Why does Redmi 9 have a headphone icon if there arenβt any?
The reason is almost always one of three components:
- π Physical contamination of the connector: dust, pile or oxidation of contacts close the circuit, simulating the connection of headphones.
- π€ Software failure: an error in the work of the audio driver or firmware (especially after updates) MIUI).
- π§ Mechanical failure: 3.5mm damage to the socket (for example, after a phone fall).
On the Redmi. 9 (model M2003J15SC/M2004J19C) The first cause is pollution, and the thing is, the connector doesn't have any protection against dust (IP-The certificate is missing and the design is prone to garbage accumulation. MIUI 12/13.
π How do you tell if you're a regular icon, like after rain or cleaning your pockets, it's the connector that's the fault, and if the icon catches fire after the upgrade and doesn't go away, the problem is the software.
Method 1: Reboot and check the connector
Start with the simplest, forced reboot, which helps in 30% of cases if the failure is temporary (for example, after connecting headphones with a custom plug).
- Hold the power button for 10-15 seconds until the phone turns off.
- Wait 30 seconds and turn the device on again.
- Check to see if the icon is gone.
If the reboot didn't help, check the 3.5mm connector:
- β Light up with a flashlight - there should be no foreign objects inside (pillow, dust, pieces of plastic).
- β Carefully shake the phone β if you hear a rustle, then there is garbage inside.
- β Do not use metal objects for cleaning (needles, paper clips) β this can damage the contacts!
π‘
If the connector is dirty, use a toothpick with cotton wool soaked in alcohol, and the movements should be tidy, in a circle, without pressing.
Method 2: Software resetting of sound settings
If the audio driver is failing, resetting the audio settings will help, and this method doesn't delete your data, but returns the playback parameters to the factory.
- Open the Settings. β Sound and vibration.
- Slip on the three dots in the upper right corner and select Reset.
- Confirm the action and restart the phone.
If there is no Reset option (some versions of MIUI remove it), use an alternative method:
##36446337##Enter this code in the Phone app as if you were dialing a number. The audio testing menu will open β select Headset Mode and turn it off.
What if the code doesn't work?
Method 3: Cleaning the 3.5mm connector without disassembly
If the trash in the nest is to blame, try a safe cleaning without risking damaging the contacts.
- π§΄ Isopropyl alcohol (70% or higher).
- πͺ₯ Toothpick or plastic spatula.
- π¨ Compressed air container (optional).
Step-by-step:
- Turn off the phone.
- Apply 1-2 drops of alcohol to a toothpick with cotton cotton.
- Carefully scroll the toothpick inside the connector 5-6 times.
- Let the phone dry for 10-15 minutes (alcohol evaporates quickly).
- Turn on the device and check the result.
Turn off the phone.
Prepare alcohol and toothpick
Do not use metal objects
Let the phone dry completely
Check the result only after switching on-->
β οΈ Attention: Do not blow into the connector with your mouth - moisture from breathing can aggravate the oxidation of the contacts. If there is no alcohol, use a dry cotton swab, but the effectiveness will be lower.
Method 4: Update or roll back firmware
If the headphone icon appeared after the MIUI update, the firmware bug is to blame.
- π Reverse to the previous version (if you know that there was no problem before).
- π Update to the latest stable version (if the bug has already been fixed).
How to update firmware:
- Go to Settings β About the phone β System update.
- Click Check for updates.
- If a new version is available, download it and install it.
How to Reverse the Previous Firmware:
It's more complicated -- you'll need to unlock the bootloader and install it through Fastboot. Detailed instructions are available on the 4PDA forum (look for a theme for Redmi 9 by model code).
| MIUI version | Famous bugs with a 3.5 mm connector | Decision |
|---|---|---|
| MIUI 12.0.8β12.0.12 | False operation of the headphone sensor | Update to MIUI 12.5+ |
| MIUI 12.5.1β12.5.3 | The icon appears after connecting Bluetooth headphones | Resetting Bluetooth settings |
| MIUI 13.0.1β13.0.4 | Permanent icon after update | Recoil on MIUI 12.5.6 or cleaning the cache |
Method 5: Repair or Replace 3.5mm connector
If none of these methods worked, it's likely that the nest itself is damaged.
- π₯ Phone falls on the connector.
- π Frequent connection of headphones with a non-standard plug (for example, USB-C β 3.5 mm).
- π§ Liquid intrusion.
Signs of connector failure:
- The headphone icon burns constantly, even after flashing.
- The sound in the speakers is distorted or absent.
- When you connect real headphones, sound goes through speakers.
π§ What do you do:
- Diagnosis in the service center (cost - from 500) β½). The master will check the chain with a multimeter.
- Replacement of the connector (1000-1500) β½). On the Redmi 9, it is an inexpensive procedure, as the nest is soldered, but easily accessible.
- Disabling the connector software (unless you use wired headphones) requires root and file editing /system/build.prop.
β οΈ Warning: Replacing the connector on your own without soldering experience can damage the motherboard. On Redmi 9, the socket contacts are soldered to a small section of the board - overheating can cause lanes to detach.

If the phone is warranty, do not open it yourself! contact the authorized Xiaomi service - repair of the 3.5 mm connector refers to warranty cases (if there are no traces of mechanical damage).
How can we prevent the problem from recurring?
To ensure that the headphone icon does not appear again, follow simple rules:
- π§Ή Regularly clean the connector (every 2-3 months) with a dry cotton swab.
- π§ Use headphones with a quality plug (avoid cheap Chinese adapters).
- π« Do not insert headphones with force - if the connector resists, check it for garbage.
- π Avoid temperature changes (condensation can cause oxidation).
- π± Update your firmware, but read the forum reviews before you do (for example, 4PDA or XDA).
If you use headphones a lot, consider a Bluetooth headset that will reduce the load on the 3.5mm connector and extend the life of the phone. The Redmi 9 has a good work with Xiaomi Mi True Wireless Earbuds or Redmi AirDots headphones, which automatically switch the sound and do not cause conflicts with the connector.
